رجاءاااااااااااااااااااا عاجلا ولكم مني جزيل الشكر والامتنان والدعاء

1. What are the two main functions of a datagram-based network layer? What
additional functions does a VC-based network layer have?
2. List and describe the ATM network service models.
3. Compare and contrast link-state and distance-vector routing algorithms.
4. Discuss how a hierarchical organization of the Internet has helped to scale to
millions of users.
5. What is the decimal equivalent of the IP address 223.1.3.27?
6. Consider a LAN to which ten host interfaces and three router interfaces are
attached. Suppose all three LANs use class C addresses. The IP addresses for the
13 devices will be identical in which of the first 32 bits?
7. Why are different inter-AS and intra-AS protocols used in the internet?
8. Describe three different types of switching fabrics commonly used in packet
switches.
9. Why are buffers needed at the output ports of switches? Why are buffers needed
at the input port of switches?
10. Compare and contrast the IPv4 and the IPv6 header fields. Do they have any
fields in common?

13. what are the full name of the following :-
ICMP, NAT, CIDR, RIP, OSPF, BGP, ATM, IGRP?

شوف في الكتاب (https://rapidshare.com/files/21235772/Computer_Networks_Problem_Solutions__4th_Ed_2003__-_Andrew_Tanenbaum_Prentice_Hall.pdf.html) chapter 5 section 5.2.4 and 5.2.5

4. Discuss how a hierarchical organization of the Internet has helped to scale to
millions of users.


5. What is the decimal equivalent of the IP address 223.1.3.27?
مش فاهم ؟؟!! ماهو الرقم مكتوب بالديسيمال ، إيه المطلوب؟


6. Consider a LAN to which ten host interfaces and three router interfaces are
attached. Suppose all three LANs use class C addresses. The IP addresses for the
13 devices will be identical in which of the first 32 bits?
7. Why are different inter-AS and intra-AS protocols used in the internet?


8. Describe three different types of switching fabrics commonly used in packet
switches.
i think u may mention (store and forward method) and (cut through method) for packet switching


9. Why are buffers needed at the output ports of switches? Why are buffers needed
at the input port of switches?
because the sender speed may be different than the receiver speed in handleting data for transmition


10. Compare and contrast the IPv4 and the IPv6 header fields. Do they have any
fields in common?
ya 3am search for it on wikipedia :)

في الكتاب ده (https://rapidshare.com/files/21235772/Computer_Networks_Problem_Solutions__4th_Ed_2003__-_Andrew_Tanenbaum_Prentice_Hall.pdf.html)هتلاقي كلام يفيدك كتييير
الحلول بتاعت الكتاب ده موجوده عندي لو عايزها أبعتهالك

السلام عليكم

أعتقد أن أي كتاب نتوورك سيحتوي على الأجوبة والحلول لهذه الأسئلة ...
أخي أعتقد أن أي شخص سيجاوب على أسئلتك سيعود لأحد كتب الشبكات ... لماذا لا تعمل المثل
بسهولة يستطيع أي شخص الرجوع لأحد الكتب وإجابة أسئلتك ... لكن هل ستكون أنت المستفيد ؟ لا أظن

مواضيع الأسئلة عامة بمجال الشبكات ... حاول أولا الرجوع لأحد المراجع مثل المرجع الموجود بهذا الموضوع ... متأكد أنك ستجيب على أغلب الأسئلة لوحدك ... وإذا تغلبت بسؤال معين عد لهذا الموضوع وضع السؤال

صدقني هكذا ستستفيد بشكل أكبر ولن تنسى المعلومة الي تعبت بالحصول عليها

مشكور اخوي .....firefox4ever على الرد ولك مني الشكر على الكتاب
مشكور اخوي.......hassan79 على الرد بس مالقيت مراجع تخص الاسئلة الا اشياء تحكي باطراف الموضوع وانا ابغاها مفصله لكن ابشوف الكتاب الي ذكر لي بالرد الاول

انــــــــــــــــــــــــــــا لكم شاكــــــــــــــــــــــــــــــر

1. What are the two main functions of a datagram-based network layer? What additional functions does a VC-based network layer have?
Datagram-based network layer: path determination and switching.
Additional function of VC-based network layer: call setup.

2. List and describe the ATM network service models.
ATM service models: CBR, VBR, ABR, UBR. See section 4.1.1 for descriptions

3. Compare and contrast link-state and distance-vector routing algorithms.
Link-state algorithms: Computes the least-cost path between source and destination using complete, global knowledge about the network.
Distance-vector routing: The calculation of the least-cost path is carried out in an iterative, distributed manner. A node only knows the neighbor to which it should forward a packet in order to reach a given destination along the least-cost path, and the cost of that path from itself to the destination.

4. Discuss how a hierarchical organization of the Internet has helped to scale to millions of users.
Routers are aggregated into autonomous systems (AS). Within an AS, all routers run the same intra-AS routing protocol. Special gateway routers in the various Ass run the inter-autonomous system routing protocol that determines the routing paths among the Ass. The problem of scale is solved since an intra-AS router need only know about routers within its AS and the gateway router(s) in its AS.

5. What is the decimal equivalent of the IP address 223.1.3.27?
السؤال خطأ
What is the binary equivalent of the IP address 223.1.3.27?
11011111 00000001 00000011 00011100

6. Consider a LAN to which ten host interfaces and three router interfaces are attached. Suppose all three LANs use class C addresses. The IP addresses for the 13 devices will be identical in which of the first 32 bits?
24

7. Why are different inter-AS and intra-AS protocols used in the internet?
؟؟

8. Describe three different types of switching fabrics commonly used in packet switches.
Switching via memory,
switching via a bus,
switching via an interconnection network

9. Why are buffers needed at the output ports of switches? Why are buffers needed at the input port of switches?
Need for buffers at input port: multiple packets arriving to the switch at the same time may need to go to the output port.
Need for buffers at the output port: switching fabric may not be faster than line speed.


13. what are the full name of the following :- ICMP, NAT, CIDR, RIP, OSPF, BGP, ATM, IGRP?
ICMP : Internet Control Message Protocol.
NAT: Network Address Translation
CIDR: Classless InterDomain Routing
RIP: Routing Information Protocol
OSPF : Open Shortest Path First
BGP : Border Gateway Protocol
ATM : Asynchronous Transfer Mode
IGRP: Interior Gateway Routing Protocol (Cisco proprietary)
